Subject: [build] Provide mechanism for listing constituent object sizes
X-Git-Tag: v0.9.8~158
X-Git-Url: http://git.ipfire.org/cgi-bin/gitweb.cgi?a=commitdiff_plain;h=ead44dba8942e85730d545e9696cdf31433942d4;p=thirdparty%2Fipxe.git

[build] Provide mechanism for listing constituent object sizes

You can now type e.g.

  make bin/rtl8139.rom.sizes

in order to see the (uncompressed) sizes of all of the object files
linked in to bin/rtl8139.rom.  This should make it easier to identify
relevant code bloat.
